The sole portionsthen connect directly with the high heel portions and the instep formsthe continuation of the central portion of the leg positioned betweenthe high heel parts. To insert heel portions in the stocking it iscustomary to separate the sole portions from the high heel parts byincisions and to transfer the high heel portions beside the soleportions in the direction of their courses to the transfer needles of alooping machine. Each transfer in the course requires, however, aplurality of top rows over the edge to be transferred, so that thelatter which will easily curl up may be conveniently handled andproperly transferred. The result is that after undoing thesetop rowsthere will remain between the transfer line of the high heel parts andthat of the sole parts a relatively broad gap which after the linking ofthe heel portions will form a slit on both sides above the heel angles,and these slits must be united by sewing later on. Apart from the factthat such a stocking is somewhat unsightly in the heel angles, itsuffers from the drawback that the strength of the highly stressed heelangles is reduced.

It has been proposed already to overcome these troubles by working inthe requisite top rows while stopping the working of the central legportion, but this would involve a special construction of a fiat hosieryframe, such as subdivided needle bars and the like, not found inordinary. machines.

According to the invention, in order to insert separately produced heelportions in a stocking worked on a fiat frame and having a leg integralwith the sole portions, the instep and the toe, the stocking is properlytransferred to two closely superposed rows of transfer needles at thepoint where the sole portions have to be separated from the high heelportions for inserting the heel portions, whereupon separation of thesole portions from the high heel portions is effected between the twotransfer rows.

This method can be applied also to such stockings in which the heelportions with their initial course have been connected already on theframe with the body of the stocking, so that subsequently only the innerlongitudinal edges of the heel portions have to be united with the bodyof the stocking structure. In every instance, the transfer needles towhich the sole portions have been transferred are preferably broughtinside beside the transfer needles holding the high heel portions into acommon plane whereupon the inner longitudinal edges of the heel portionsare transferred to the transfer needles of the sole portions. Transferof the stocking is preferably carried out on a transfer device or alinking machine from whose row of transfer needles parts may be swungoutl", so that these swung-out parts will be 10 positioned above theadjacent needles of the transfer needle row. v

Two embodiments of the invention are illustrated in the accompanyingdrawings, in which Figures 1 and 2 show how the heel portions with 15their initial courses are connected already on the fiat frame with thebody of the stocking; Fig. 3 shows how a stocking according to Fig. 2 istransferred'above the fixing points of the heel portions to two closelysuperposed transfer needle 20 rows; Fig. 4 shows how after theseparation of the high heel portions from the sole portions the transferneedles of the latter are brought on the same plane with the transferneedles of the former; Fig. 5 shows how afterwards the inner 25longitudinal edges of the heel portions are transferred to the transferneedles of the sole portions; Fig. 6 shows how a stocking structure istransferred without heel parts connected thereto on a flat hosieryframe; and Figs. 7 and 8 30 are, respectively, a front and top View of aportion of the transfer needle row of a. looping machine.

Referring to the drawings, the stocking structure I is transferredcorrectly, at the point where 35 the insertion of the heel portions 2requires separation of the high heel portions 0 from the sole portions4, to two closely superposed transfer needle rows 5, 6, 6', whereupon bysuitable means,

such as a very thin knife, separation of the high 40 heel portions 3from the sole portions 4 takes place on the chain dotted line in Fig. 3.It is therefore no longer necessary to interpose additional top coursesbetween the two transfer rows,

only a certain separating course being needed, 45

and both the end course of the high heel portions 3 and the initialcourse of the sole portions 4 will thus be correctly held without theusual loss of courses. The transfer of the parts I and 4 may be effecteddirectly to the needles of a corformed transfer device whose transferneedle rows 6, 6' for the sole portions 4 are arranged on fasteningmeans capable of moving 180, 50 that the transfer needles of thesemovable parts may be brought from a plane common with the needles forthe high heel portions 3 above the transfer needles of the high heelneedle row 5. If the transfer is to take place directly to a loopingmachine, the transfer needle row thereof should be correspondinglyformed. The needles of the transfer row 5 for the high heel portions 3are then secured to the usual bar 1, but the needles of the transfer row6, 6' are attached to the fastening means 8, Figs. 7 and 8, which can beswung out of the needle row to the extent of 180. The arrangement issuch that the parts 8 will be between the needles of the transfer row 5when all needles are on the same plane. The arms 9, l insure themobility of the parts 8.

After the transfer needles of the needle row 6, 6' of the sole portions4 are brought on the same plane with the needles of the transfer row inthe 'manner described, the inner longitudinal edges ll of the heelportions 2 are then trans- I ferred to the needles of the row 6, 6- soas to permit linking of these edges.

By means of the method and device described it is possible to transferthe separately worked heel portions 2 both on their initial course I 2and on their inner longitudinal edges ll. Then the foot with toe, instepand sole portions is worked on directly to the leg and the entirestructure transferred as stated. After separation of the high heelportions 3 from the sole portions 4 the transfer points of the row 6, 6are brought on the same plane with the transfer points of the high heelportions 3. Then the initial courses l2 of the heel portions 2 aretransferred to the transfer needles of the needle row 5, and their innerlongitudinal edges II to the needles of the transfer row 6, 6'. Iftransfer takes place directly to a looping machine, the heel portions 2may be linked in directly.

It is further possible to transfer the heel portions 2 with theirinitial courses l2 to the needles of the machine producing the stockingstructure and to bring them during the production of the leg under theknocking over member l3 as shown in Fig. 1. If the leg is then finishedwith its heel portions 3, the heel portions 2 are brought on the memberl3 and thus during the further working of the foot bound into the bodyof the structure I, Fig. 2. This stocking structure I is thentransferred slightly below its heel joining points l2 to the needle rows5, 6, 6', Fig. 3, whereupon separation of the high heel from the soleportions takesplace again. After the transfer points of the soleportions 4 have then been brought on a plane with those of the high heelportions 3, as shown in Fig. 4, the inner longitudinal edges ll of theheel portions 2 may be transferred also to the needles to which the soleportions 4 have been transferred. Only the inner longitudinal heel edgesII will then be linked with the initial sole courses. The end course ofthe high heel portions 3 is finished off only to prevent unravelling upto the binding-in point of the heel portions 2. This method is superiorto the one described before in so far as the points of junction of thehigh heel portions 3 with the heel portions 2 are not conspicuouslyvisible.
